Internet security












NetCenturion is a TCP/IP packet filter for Windows 2000 and XP that protects your computer from unauthorised access and attacks while connected to the public Internet. NetCenturion can make your computer appear invisible from the Internet and can protect vulnerable Windows services such as file sharing.  It does all this while you continue to enjoy uninterrupted web browsing, e-mail, downloading and other Internet activities.

NetCenturion is open source.  It may be freely used by any individual for personal or private use or for their business without any restriction or charge.  Companies, organisations or governments may not use it without a license.  In no case may NetCenturion be used to deprive anyone of life, liberty or livelihood.
